If you’ve ever seen the 1960’s live-action Batman TV show, you’ll know that one of the defining characteristics of the show was its use of comic-book style words overlaying the action scenes, a technique pioneered in comic books by Roy Crane:
It was Crane who pioneered the use of onomatopoeic sound effects in comics, adding “bam,” “pow” and “wham” to what had previously been an almost entirely visual vocabulary. Crane had fun with this, tossing in an occasional “ker-splash” or “lickety-wop” along with what would become the more standard effects. Words as well as images became vehicles for carrying along his increasingly fast-paced storylines.
